Chery Ant fails to fully charge due to short circuit or water loss faults. Short Circuit Fault: When a short circuit occurs in one of the small batteries in the electric vehicle's pack, charging the vehicle will result in the charging light not turning off, commonly referred to as the battery not being fully charged. The usual solution for this issue is to replace the entire battery pack, which resolves the problem of the charging light not turning off. Water Loss Fault: This situation is relatively common. Generally, if the electric vehicle's battery has been used for more than three years, water loss faults often occur. The typical symptoms include severe battery overheating during charging and the charging light not turning off.

My Chery Ant also had a similar charging issue where it wouldn't charge to full capacity. The main reason is likely the Management System (BMS) kicking in to protect battery lifespan by automatically limiting charging capacity, especially in high or low-temperature environments. Frequent fast charging can also cause this, as repeated high-power inputs may overheat the battery and trigger protection mechanisms. Another common cause is charging equipment problems, such as poor contact with the charging gun or unstable home voltage. I once solved it by simply changing the home power socket. Battery aging is another key factor—after years of use, the energy storage capacity naturally declines. I recommend checking for any fault codes in the vehicle, trying a slow charger instead of public fast-charging stations for gentler and more reliable charging. Also, avoid leaving the battery at full charge for extended periods or parking in extreme temperatures to help maintain battery health.

It's quite common to see the Chery Ant not being fully charged. I believe this is often related to software settings, such as the built-in management system setting a safety limit to prevent overcharging. Battery aging should not be overlooked either; the Ant's lithium-ion battery naturally degrades over time, reducing storage capacity. Another factor could be the charging environment: if the weather is too cold or too hot, battery efficiency decreases, and not reaching full charge is normal. There might also be issues with the charging cable or charging station, such as oxidized contact points causing unstable current. Personally, I've changed my charging habits to avoid charging to 100% every time, stopping at around 80% instead, which is better for battery longevity. I recommend owners regularly visit service centers for battery checks to identify issues early.

My Little Ant also experienced the issue of not charging to full capacity. Most likely, it's due to health degradation—capacity shrinkage or internal damage after prolonged use. Compatibility issues with the charger could also be a factor: if the original charging cable is loose or damaged, power supply interruptions can reduce effectiveness. On the software side, the BMS program might impose limits, with the system automatically preventing a full charge to avoid overheating risks. Environmental factors like low temperatures can also slow charging and prevent reaching the maximum level, which is common in winter. The solution is simple: first, try different charging stations or switch to slow-charging mode. Also, avoid regularly depleting the battery before charging—topping up midway is better for daily use.

Regarding the issue of the Chery Ant not being able to charge fully, I speculate that common causes include internal degradation or cell imbalance, where prolonged use leads to some cells failing first and affecting the overall performance. External factors such as charging equipment malfunctions, voltage fluctuations from fast-charging stations or household sockets may trigger protection mechanisms. On the software side, the BMS (Battery Management System) strategy might limit charging to 90% to extend battery life. When temperatures are too high, the system automatically intervenes, reducing charging efficiency. For maintenance, it is recommended to clean the charging port of dust and ensure all connections are secure. If self-checks prove ineffective, it is best to visit a professional workshop for diagnosis. Additionally, adjusting charging habits—avoiding prolonged deep discharges or leaving the battery at full charge for extended periods—can help prevent further issues.

When encountering the Little Ant not charging to 100%, my first thoughts are aging and protection mechanisms. The BMS system may temporarily limit capacity after fast charging to prevent damage. Hardware issues like dirty charging ports or damaged wires can cause poor contact and interrupt charging. If the ambient temperature is too cold, the battery's chemical reactions slow down, preventing a full charge. Poor maintenance, such as neglecting charger cleaning, can also cause malfunctions. It's recommended that owners conduct self-checks: try slow charging and different charging stations to confirm if the issue is consistent. In the long term, regular battery maintenance and adjusting the charging routine to around 80% can help alleviate the problem. Safety first—don't force a charge; it's wiser to get it checked promptly if there's an issue.
